Which of the following statements is true about damping in measurement instruments?

Damping in measurement instruments is crucial for achieving stable and reliable readings. When a measurement instrument, such as a dial gauge or analog voltmeter, experiences oscillations—where the pointer swings back and forth around the final value—it can lead to confusion and errors in reading the measurement accurately. Damping is employed to control these oscillations and help stabilize the reading, allowing the pointer to settle on a steady value. This process is vital for enhancing the user’s ability to obtain a precise measurement without the distractions caused by excessive movement of the pointer.

While damping can have secondary effects such as influencing the responsiveness of the instrument, its primary purpose is to reduce oscillations of the pointer, thus improving clarity in readings. Options related to speed, accuracy, and calibration do not encapsulate the core purpose of damping as clearly as this correct statement does.
